subject and negotiators and officers. what we see now has a look of a negotiation and surrender-type thing. i'm not saying that's what it is. this could be maniy is narrows, but on the surface, this is the tactics you would see when you have a deliberate negotiated surrender. >> i have been given a statement from -- another part of the story unfolding. robert la montan from dartmouth in new hampshire. the university has learned that a person being sought in connection -- >> you are listening to live coverage from the today show on nbc news. you are watching continuing coverage here on msnbc. this hour a teenage terror suspect closed down one of the nation's largest cities. we continue to watch live pictures from watertown,

massachusetts as breaking news continues on the lockdown and unprecedented dragnet in and around boston. if you are just joining us, this changed over the last two hours. they are focusing on three and not two. a third person added as an accomplice. another ied and reports over an hour ago of that. and we are now hearing from people who are close to the suspects, getting a sense of who these men are. this is what we know. the entire city of boston and surrounding suburbs effectively shut down. the focus on suspect number two on the right part of your screen believed to be holed up somewhere in the pictures that we are showing you right now. he is now identified as 19-year-old zhokhar. number number one, his brother was 26-year-olds, tamerlan.

one was born in curd stan and the other in russia. they have been living here in this country for about a decade. in watertown, nbc news justice correspondent and atf agent james cavanaugh and analyst roger cressy. live in watertown, we were listening together as kerry sanders was moved further and further back. what are you seeing? >> he is a few blocks away from here, but we are not hearing anything that he is hearing. it's quiet in this part of watertown. the helicopter that had been circling for the past few hours is no longer here. we have seen tactical units leave and others come back in. we haven't seen anything like kerry has been seeing a few blocks away from where we are standing. we don't want to give away too much because the police asked that we don't give out tactical

information, but we are going on hour ten of a lockdown. people are not outside. maybe all of four or five residents come around to the area. that's very unusual whenever there is a media staging area people ask what is going on. we have seen none of that. people are heeding the warnings to stay inside. police have been going from door-to-door trying to see if they can find suspect number two, the guy in the white hat. if he is hiding out here, there is suspicion he s. the entire area of boston is on lockdown. that's over a million people. they want to make sure that everyone is staying safe and if this guy is out there, he is not going to get lost in a crowd. they want to narrow down the opportunities to get him. it's easier to find him. harder if you are going to see a lot of people walking around. they have been going door-to-door.

we have not heard anything in the way that kerry sanders has. it has been quiet. it's not much more i can tell you from the location just because it has been quiet. >> thank you very much for the latest. stand by and we will get back to you later. let's bring in pete williams who has been watching this as well. what are you hearing? pete williams has been watching this story for us. we have michael with us as well since overnight. michael, early on today about seven hours ago, you reported the first suspect that was confirmed dead. what are you hearing at the moment from your sources? >> at the moment, we are all waiting on the results to see if they have the primary suspect surrounded. if they are going to take him into custody and then the

alleged accomplice on the connecticut police who took the amtrak train in connecticut. a couple of things. we are still standing behind the principal staging area where we had convoys and military vehicles and trucks and buses and motorcycles as though they were planning for a confrontation of some kind. the intensity of the activity seems to have awaited. we suggest that the reports of the cordoned off area may be real and that's where the principal confrontation will be taking place. the thing to remember is the ied that was found in the city of charlestown was the real reason that they put the entire city on lockdown.

the fear that even if they catch this guy and his accomplice, he may have booby trapped the city as it were with other improvised explosive devices and how they will ever feel confident and how quickly it takes them to feel confident that they let citizens walk the streets is unclear. when there is a concern this guy may have done that. that's the principal concern at the moment. i want to mention one other aspect of this which we talked about a little while ago. we found a you tube account under the name of the elder brother who is now dead. it's a clear jihadist you tube account that posts videos of al qaeda and the black banners which is an al qaeda rallying

cry based on the ultimate battle of good and evil with the islamic army and the forces of evil in the world. this is the first suggestion of what the motivation might have been. now, it's very hard to know for sure whether that is in fact the same guy we are talking about. he has the same name and it was posted four or five months ago and there multiple postings, but it does perhaps give a lead. >> a lot of questions whether it's domestic or international. you have been careful throughout your reporting i want to go to clint van vandt fbi profiler. clint as well as we are getting

reports -- we don't have clint yet, but we will later. roger as well as james cavanaugh. former atf agent, from the reporting that you are hearing from michael and the possible links if this you tube account is indeed linked to one of the suspects, what's your reaction to that? are you there? >> i'm here. >> what would your reaction be to the report about a link to the you tube account showing international ties to militant groups here? >> it's important information for the commander who are handling the barricade situation that we are watching and the negotiators that are probably going to be dealing with him and may be talking with him right now. to have an idea of where they are coming from from the family members in the washington area maybe from his father and

anybody who knew him and the carjack citizen and they will try to get a dialogue going with him and see what he is trying to do. when people get into the modes of they are going to blow up public places, they have a reason for it. it may not make sense to the rest of us, but it makes sense to them. they are going to want to try to explain it. the negotiators are going to be willing to listen. that's to save his life and apprehend him safely. that's the overall goal. when you have been his brother with a bomb strapped on him last night, he could have a bomb strapped on him. he had cases like that. we don't let the person with the bomb walk out of the house towards the tactical operators of the s.w.a.t. team. he's not going to be allowed to walk towards them. he would be shot. he would be willing to talk or decide he was going to kill himself or surrender.

>> terrorism analyst roger cressy with us here. roger, what is your thought? we have been discussing this domestic or international link with the develop and the link to the you tube account. the question as to why now that we know the who, what is your thought at this moment in terms of the chechyan links and what that might mean and the insurgency on that part of the country? >> right now it means nothing. we all need to be very careful of any type of links we draw and whether or not this video is in fact related to one of the brothers and would just be really, really careful. i think what james just said about the tactical situation is where we should focus. any type of information that can be gathered from relatives and acquaintances that if he is holed up and they are trying to get him to surrender, any data

they can provide that will allow him to make ta decision and not be killed in the process is where we should be focused right now. there will be plenty of time for the broader linkage analysis and we are way early this that. >> roger, as we watch the live pictures, we are about to get a news briefing in about the next eight minutes or so. some of the resources from law enforcement and military on the ground and some we can see here. helicopters from police and 50 guardsmen and more military humvees coming in earlier and dozens of law enforcement if not hundreds and vehicles scattered across water and the city. is this enough based on what you understand they are trying to do at the moment? >> it's a tremendous deployment of resources and certainly you have to defer to the judgment of the officials on the ground if it's the right amount. obviously the more, the better in this type of situation. you have to look at the possibility as michael mentioned

earlier that there could be additional devices placed around the greater boston area. you also have to look at any other potential components to what could be a broader conspiracy. we don't know the steps they took to first deal with him and try to get him to surrender if he is holed up and secondly to understand where there might be additional devices around the greater boston area and third, to identify any other individuals who might be in any way associated with the brothers is where the priorities are right now. >> clint van zandt joins the conversation and any other individuals that might be involved in this in the last two hours. there is an accomplice and a third person they are discussing in this investigation. how much broader might this go? >> we are going to leapfrog off each person. we are going to look at their

cell phones and internet conversations. mail, anything else. when we start to make this linkage analysis, realize right now the most important thing is that no one else gets hurt. we have this individual and we are told barricaded in the house and perhaps with weapons and explosives. let's get him out and we need the best tactical information we can get. as a former fbi negotiator, the more information i had, the more reason i could give a barricaded subject to come out without anyone else being hurt. that's a primary concern and there is a lot of men and women out there now. they have a lot of things going on at one time. it may well be trying to talk this one individual out. all of these collateral investigations have to be done on a potential of other devices and on the potential of coconspirators. >> 19 years old, the suspect that is want and believed to be holed up somewhere in watertown.

at the moment, he is 19 years old and we have been in this for about six or seven hours since we had our first conversation earlier in the morning. what would you do as a negotiator and as a profiler. what's your strategy as you speak to him? >> i want to wear him down and make him very comfortable, but wear him down. look, you and i have been up since 1:00 in the morning and he probably didn't sleep all night long again. whether he is running on power bars or drugs, we don't know. she going to start to come down soon. the negotiators want to help him do that and as he is just -- he and his brother tried to escape the area by robbing a convenience store and stealing cars and police officers and things like this, he is frantically trying to figure a way out f. we know where he is out and we have him barricaded, time is on the side of the authorities.

we want to get him out alive. we don't have to be in a hurry in a haste. there is a lot of commerce that shut down. millions of dollars being spent. we need to know what he knows and why he did this and who else is involved and the potential of other devices out there. for all of those reasons, this is not a tv thing where you bring it up and fill the house with gas. we don't have to do that right now. we have more to gain by bringing him out our own way than trying to bring him out with gas and weapons. >> we hear that the russian embassy in washington, d.c. offers condolences to the president of the united states. clint, as we continue to follow this, nbc news hearing that two sources including the boston police department saying that some blood was found after last night's confrontation in watertown. that blood right now being

checked to see if the brother that we have been talking about that is now at large continues to be on the loose and was injured or wounded. in the discussion in the negotiations, how would you factor that in? >> for example, i had a hijacking in an airport one time where the individual had a horrible headache. one of the negotiation ploys was to introduce aspirin. we had a hijacking where an individual had a entire for a cigarette. we introduced cigarettes into that. whatever his needs might be, the negotiator is going to be there and we are going to try to center attention on him and let him know that we care about him and if he can hear my words, listen to that negotiator. trust a negotiator. they are there to help you. you are in a volatile situation. you have a message to deliver. let the negotiators and the authorities help you deliver that message. otherwise you are going to go

down in history as a poor diluted soul. i don't think he wanted to do that for the memory of his brother. >> let's go to michelle kosinski who has information on the suspect's family. we are waiting for the briefing and the pictures on the right side, it's about to start, we believe. before that happens, what are you hearing? >> interrupt me if you are about to get new information. what we have been gathering and we are seeing this coming out in the russian press, we have not spoken to the family ourselves. some family in the u.s. has also been contacted by the press. here's what we know. the associated press was able to reach the father in the russian republic. there have been strong separatist movements and war against the governments there as well as the governments of russia. these are parts of russia. the family is from there and

where they lived. the father is still there in one of the republics where the family lived at one time. he said his younger son is a true angel and a second year medical student here in the united states. he didn't make comment about the other son. there was also a head master of a school also there that the two sons attended and they said this was a family of six. two parents and two sons and two daughters. they had moved from one russian republic to another in 2001 as refuge refugees. we 99 some way at least they were affected by the trouble in that region. the head master said after one year in 2002, the whole family moved to the u.s. it's been easy for people to say well, they from this region where there have been the movements and foreign fighters attracted there.

a strong islamic jihadist movement. these were kids when they moved to the u.s. the youngest one was maybe 8 or 9 years old. they were affected by it, but they grew up and went to school in the u.s. where in some ways it seemed they did quite well. the younger one was a wrestler. friends have been interviewed and described him as a regular guy and very quiet. never heard a bad word about him. very nice. he went to parties. seemed very much american. the older son we know was a boxer. it seems he won a title at some point. when you look at what seems to be the social media sites, one particular russian social media site, if they belong to these sons, the younger one was apparently posting some links to sympathetic groups with the chechnyan separatist movement.

he described his world view according to what's out there if it is indeed his as islam. he other brinks to certain other sites that were sympathizing with the cause for independence. there was a photo essay that was done on the older son as a boxer. in it he was quoted as saying i don't have a single american friend. i don't understand them. the way people described them is very much assimilated into american life. this is where they were educate and had some friends at least according to some people who have been interviewed. on the other side, if these are the social media accounts, they did have simple eags with politically what was going on back home. we don't know too much about other members of the family being involved in and what the beliefs were. the father did not talk about that.

two uncles were interviewed. he said i'm sorry about this. if they were involved i feel sorry too. the other uncle said he hasn't spoken to the boy boys in a long time and said the older one was a loser. >> a great overview of the family as we have been learn being the suspects. the brothers are 19 and 26. response from the father that she related to us as well as i have more information as we wait for that news briefing on the ground there in massachusetts. the russian embassy in washington saying that president putin sent condolences to president obama following the terrorist attack in boston. a spokesman saying the two brothers never registered with the russian embassy in the russian consulate in new york and they posted this message on their website. i will read it to you. it said vladimir putin sends

condolences to president obama following the attacks in boston and condemned the barbaric and said it requires gloenl community effort. that in part from the russian embassy. condolences from vladimir putin. roger cressy still with us as we wait for the briefing to start shortly in a matter of minutes. we were hearing for michelle kosinski. we got a better knowing of who they are and also the statements from those who knew the current 19-year-old. we will go to the "today" show. stand by. let's take a listen. provoked this? >> um, being losers. able to

settle themselves as you can imagine. anything else to do with religion and islam is a fraud. it's a fake. i knew them when they were kids. we are muslims and ethnic >> if that happened, most likely. we made their life bringing bread to the table and fixing cars. he didn't have time or chance or anything, an option. he has been working. that's it.

no, no, no. i have not been in touch with my brother. i don't know anything about that. no, my family has nothing to do with that family. pardon me? of course. we are ashamed. we are ashamed. they are children of my brother. who had little influence of them honestly as much as i know. he had little influence of them. it's a personal. i didn't like him. i just wanted my family to be away from them. that's it. again, the only -- i say what i think was behind it, being losers. not being able to settle themselves. there by hating everyone who did.

i have been in the united states -- they came early since 2003. >> why are they angry? >> they came to -- when they moved to the states, they came to cambridge area. >> '? >> they emigrated and they received asylum. >> were they going to school and working? >> yes. they lived there. >> did they go to college? >> i hope they were. i don't know. when they grew up as i said, me, myself, and this family had nothing to do with them for a long, long time. >> how do you feel about america? >> last time i spoke with my -- about 2009. >> how do you feel about america? what do you feel about the united states? >> i teach my children and that's whey feel myself. this is the ideal microworld in

the entire world. i respect this country. i love this country. this country which gives chance to everybody else to be treated as a human being and to just to be a human being and to feel yourself as a human being. that's what i feel about this you can give us your proper last time in is tsa rni. >> i don't know. i have seen them as kids. even if i slightly have been aware that they were involved in this, i would be the first one to bring them into responsibility. were they caught up in -- >> they never have been in

chechnya. chechnya. they are fiscal people. >> were they born there? one of them was born there. a neighboring region. >> you haven't seen them in years? >> i haven't seen them in years. >> when you saw the pictures, did you recognize them? >> only this morning when i was contacted at 7:00 with reporters. >> when you saw the pictures on the news last night? >> when they said have you seen the pictures, my wife opened up the internet and on aol, i saw a picture. >> what would you say to him? >> i would say if you are alive, turn yourself in. and ask for forgiveness. from the victims, from the injured and from those who left. ask for giveness from these

people. we are not requiring forgiveness in this family. he put a shame on our family. he put a shame on the entire chechyan ethnicity. everyone now names the word chechyan. they put that shame on the entire ethnicity. that's what i would say. turn yourself in. whatever, whatever you do, put yourself at the discretion of those who are here. that's what i would say. not yet. [inaudible] >> the last time i spoke with them, that was about three months ago maybe. no, no. >> where were they born?

>> they came here from curd stan. i am not saying losers, i am saying those who are able to make this are only losers. that's what i say. there is no idea that they may follow. thank you. >> what do you do for a living? >> i work. thank you very much. one more thing. from now on, i dearly ask you to respect our property. again, with the families of-those who suffered, we are sharing with them their grief. i am ready just to meet with them and kneel in front of them seeking that forgiveness.

again in the name of the family, that's what i would say. therefore, please. respect our property. >> thank you, sir. >> there the uncle of the anger for his nephew, saying that if you are alive, turn yourself in. ask for forgiveness. he is also saying the last time he had seen them is about four years ago. he did give us a better understanding of their background. absolutely upset and emphatic about what he said was shame to his family and shame to chechyans. roger, you were listening along with me. as we listened to tsa rni, you put together the information from others as we get a sense of

who he is and what's your thought? >> that was a pretty powerful statement by a relative. a couple of points i want to make up front. regardless of their motivation and regardless of their links and regardless of why they did what they did, we need to be careful not to paint a broad brush against a particular ethnic community and particularly a community in the greater boston area. we all as we go forward are keeping that in the first and foremost in our minds. i thought he did a good job of saying this is the act of two individuals. it doesn't reflect on the broader family or broader community. that's an important point to keep in mind. the sources of motivation of why they did what they did is what we will be focused on. these kids were facing what we have just heard. there was a disenfrance chizment

and isolation and there was anger involved. all those things together can lead you to individuals who decide to do things on their own or were influenced by external sources. we simply don't know yet. these are other pieces of the puzzle or as we used to say when i was in government, building the mosaic and understanding what it looks like to understand all the elements of a terrorist event. weer getting bits and pieces and what the government is doing is going through channels to better understand the broader family network of individuals they know potential travel and as clint van zandt said, there will be a lot of analysis of data and digital analysis. the two things terrorists do that give governments an advantage is when they talk and travel. that's what the u.s. government will be doing looking at the origins of this. we will get information quickly, i believe. >> par cannot underline that enough. you have to be careful about the

links being made and the pictures we show. understanding that it's possible that the suspect could be watching and listening to everything that we say and therefore and thus we are watching and being careful and selecting the video and of course the data that is released. at this moment at the half hour, we continue to watch what's happening on the ground and watertown, massachusetts. this as helicopters are in the air. a million people still asked to stay inside. a city on lockdown. this is unprecedented. one of the united states's largest cities at the moment closed down because of this 19-year-old. a teenager. he say suspect believed to be holed up somewhere in watertown, massachusetts. we have over 3 1/2 nautical mile radius, a no-fly zone up to 3,000 feet over this area. 20 blocks originally as our

harry sanders saw on the ground. he was being asked to move several times. we had nbc's ron allen following this. he was in watertown earlier and moved to a different location and following this story for us this morning too. what are you learning? >> richard, i'm in cambridge a few blocks down from the suspect's home. there is a heavy presence there. the area is blocked off as you can see behind me. the house is down that street in that direction a couple of blocks down. we have been moved back as bomb detection units have been brought in. we understand from the producer who had a vantage point that there is a lot of focus on a couple of vehicles. one black suv and a silver vehicle. they have taken things out of the cars and there officer who is have weapons and the weapons drawn. the area was described as being

tense. they were trading weapons on windows trying to make sure the area was secure. nothing like that out here. this area is evacuated and there a lot of people from the neighborhood standing in the streets trying to understand and trying to hear what's going on. when you think of cambridge, you think of harvard and mit. this is a different neighborhood of cambridge. the house where the upon suspect lived is described as delap dated. it's not an elegant place. this is a family that was a working class family. the older young man who was killed was a student at a local college. a branch of the university of massachusetts. the younger one was a student at a prep school here in boston. we don't know a lot about them. they are amazed at who the young

men were and they were involved in this operation. one was a wrestler and the other was a boerks. they came about ten years ago and lived here for about years in the neighborhood. they are trying to piece together what happened. we are not far from mit where the officer sean collier was shot last night and ambushed by the suspects. he was single and on the force for a couple of years. his commanding officer said he was a young man who was one of the guys who really looked at police work as a calling. he was born to be a police officer. 26 years old and single. being mourned in the community. that's what we have here now. a lot of police presence focused on the community and the street where the suspects and their

mother and two sisters lived. the area evacuated. heavy police presence and the area that is somewhat tense and for the most part the area is clear trying to understand what's going on. what this family was all about. >> ron allen from nbc news covering two of them. on your screen right now, live pictures from a helicopter over top. earlier on they were unable to fly. there was a no-fly zone over certain areas. we are watching as they zoom in in watertown. an area that is about 32,000 people and separated from the rest of the other areas there in boston. we are also waiting for a news briefing. that was supposed to start about 15 minutes ago. clint xanthopoulos and

now that you have been looking at the data and trickling in over the last eight or nine hours, it seems uncanny from a person that is watching for the outside in how things have changed so quickly and in a short amount of time. what's your perspective as a former fbi profiler and a professional watching this information come in. >> it's good to see the investigative agencies pull this together and realize 48 hours ago, we didn't have a name or a picture. we knew we had dead and wounded in boston. now we have one subject down and another subject identified. we have a third subject barricaded. they moved so quickly and it's not just nationally, but internationally. they are going on across the

united states and it's being pulled together quickly as we try to understand the motivation and who else they might be working with. the 26-year-old was decease and he was the boxer of the two. he was the leader and the more dominant of the two brothers. trying to find out what he was doing in life. he would have been the follower and he doesn't have his older brother to follow. he has to make decisions 100% on his own. if we can get him located and start with the dialogue, we can perhaps substitute an fbi and atf and police negotiator for that adult or mature type of figure and try to help him and give him a reason to come out alive. >> we are talking about a

19-year-old, a teenager. does that affect who you decide should speak with him? at 19, just finishing high school. a very young person here and the pictures we have been able to show show a very young person. >> it is. when we know his father stayed in russia, the dominant male role model he may have had is his 26-year-old brother who is now deceased. should they get a chance to talk to him will try to insert themselves as somebody who cares and is trying to help him. they are not going to be a father figure, but they may take over for that older brother role, trying to be somebody that he can bounce ideas and thoughts off of to try to help him come to a decision to come out alive. >> we have heard here that they brought in six or so porta

potties and this could go on for sometime. i wanted to extrapolate that from them moving in such equipment. they continue to watch a very busy scene. these live pictures from the helicopter above. absolutely packed with vehicles. it appears to be tense. you see some that are white and green and i don't know what has been happening today. what is going to be happening in the next one or two hours that will be crucial or really looking at a day or two? what is the critical time frame? >> realize this individual, this young man has probably not slept all night. he and his brother started committing these criminal acts last night and have been on the run ever since. negotiators will keep talking and this guy will burn out of energy very quickly. he is going to need help and going to need a type of

sustenance. we may strike a deal to send food in. it depends. realize what we don't want to do is if we have him located, we don't want to rush this process. we know in colorado, when that terrible movie theater shooting took place and when we went to the residence of that individual, it was booby trapped. that potential exists here too. law enforcement wants to enter on their own time and take their time. they don't want to do a tactical entry unless they have no other choice for fear that somebody could get hurt to include this young man and people in law enforcement. >> we have former agent james cavanaugh with us. james, if you are with us, we have three crime scenes as clint has been talking about. that is part of the mosaic. what would your strategy bes we enter in? what is more or less hour 13 of

what started yesterday? >> i agree with everything clint said and if i was commanding the tactical operation and trying to negotiate with the guy and the major talka thon. the negotiators really do want him to come out on his own. there is humanity here. we want him to surrounder. he is the guy with the information. we talked to roger about the community and all that information. he is exactly right. i agree with them. for the instant scene, you just have to get that information from him. >> thank you so much there for your perspective. james cavanaugh and kerry sanders has been watching this story for us. he has a report and we will get to that. i believe we will listen to a bit of sound from the uncle that happened a little bit earlier to say this. >> here put a shame, he put a

shame on the family. he put a shame on the entire chechyan ethnicity. because everyone now names the play with the word chechyan. they put that shame on the entire ethnicity. that's what i would say. turn yourself in and whatever you do put yourself at the discretion of those who are here. that's what i would say. not yet. last time i spoke with them, that was about three months ago maybe. no, no. [inaudible] they came here from curd stan. >> where were they burn? >> in curd stan.

i wouldn't say losers. i am saying those who were able to make this are only losers. that's what i say. there is no idea that they may follow. thank you. >> what do do you for a living? >> i work. i work. thank you very much. more thing, from now on, i dearly ask you to respect our property. again, with the families of -- those who suffered, we are sharing with them their grief. i am ready to meet with them and bend in front of them and kneel in front of them seeking that forgiveness. in the name of the family, that's what i would say. >> there is the uncle of the at

large suspect. kerry, what do you say? nbc's kerry sander who is has been following the story therefore in watertown pushed back several times in the morning as the cordon has been moved. >> we are on arsenal street in watertown. . >> go ahead. >> yes, i am. you can hear me? it's windy, but i think we have got you. i am on arsenal street, but it takes you up to school street which is where that traffic light is. i will step out of the way so we can zoom in. we will take you down the street here because that's where we were earlier today. to tell you the truth i lost track of time. down here at one point, we were jogging down with officers. officers had their weapons pull

and shotguns were out with rifles and pistols and heading down the street. we were jogging with them. as we approached an area where officers were taking defensive positions behind cars, some of the officers turned around and started telling everyone to get back. i took a position mimicking the officer i saw in front of me. as i was down looking down the sidewalk, i saw what appeared to be a body. i saw a bright turquoise shirt and something crumpled over there and the officer had when i was looking directly at his glock, nine millimeter directly aimed at that what i thought was a body. then other officers moved in that obscured my view. they started pushing us back. i stayed there for a little bit longer, but the officers came and said you have to get back. they pushed us back, back, back and the really big surprise is when they yelled get down, get down. we had to take our defensive

positions on the sidewalk and laid out. up here we had snipers taking positions. they said if you knew what was going on, you wouldn't be where you are. we pushed further back. harrowing, but the officers who were there, some are still there. many of them have since moved out. i think the excitement of that area is going into a lull. i suspect it is one more crime scene they are looking at and treating it i guess if that was a body or maybe if it wasn't, that it may be a device that could be potentially a bomb. we know the pressure cooker bombs have a tremendous force and we know that now. the idea of pushing us back is probably a good thing. i am surprised some of the officers who are as close as they are, about every officer out there is wearing a bulletproof protection. i can tell you that much. richard? >> we are watching pictures, new

video of the suspect's homes. you can see law enforcement here reaching into a silver vehicle that is right in front of the suspect's home. just getting that into msnbc. kerry, as you report, the situation has changed. the concern of course is this is an armed and dangerous suspect. they were throwing ieds out of their cars as they were fleeing. the older brother found with a bomb strapped to his body, the at large suspect then escaped rolling over his brother whether he knew it or not, that happened. when you look at what's on the ground, it quieted down a bit. have the officials indicated at all what some of the dangers might be? if you knew, you wouldn't be close to this. all right. kerry sanders having

communication difficulties. >> i wish i could you they would give a syndication. they are so focused on what they are dealing with, they have been told don't talk to the media. >> we can hear you, kerry sanders with the latest that he's been pushed back, the cordon has been broadened and broadened. clint van zandt, this is ever-changing. the interesting part of the conversation you and i just both heard, was that law enforcement officials saying if you knew what we knew about this location, you wouldn't be this close. ha do you surmise from that? >> well, i surmise from that that they have reason to believe there's additional explosives at that location. i mean weapons i think are obvious, but explosives could very well be at that location. but, look, from a negotiations from a law enforcement perspective, there's no shots being fired. there's no bombs going off.

so what looks like nothing going on is exactly what law enforcement wants it to be at this point. >> this new video coming in from cambridge, massachusetts, in front of the home of one of the suspects. we've been in this discussion before. the concern about booby traps, we were looking at the video as they were looking at cars in front of the suspect's home. as they go from location to location and there's three crime scenes at the moment, that concern of an ied is real. it is evident and we've seen it in the past. in cases. >> yeah. it is, but they've got the good fortune of a lot of resources. they have atf who do these things every day. they have fbi, i'm sure they probably have military bomb disposal teams on scene. and in a situation like this, you have enough resources, so you can prestage, in this case, bomb techs, bomb disposal units

at different locations. you don't have to run from point a to point b to point c. so this is the time to deal with it when you've got this maximum number of resources, use them, use them properly. and it gives you time, realize just like we want the subject to get tired, law enforcement is going to get tired, too. there are police and fbi agents who have been up and without sleep, too. if this goes on much longer, we have to start working into shifts and that has to be thought of also. so there's a lot going on right now. >> i want to bring in don begino, former secret service. don, as we look at the developments so far this morning, we've had the great perspective there from clint van zandt, the former fbi profiler, and we have james cavanaugh and roger cressey also with us. what's your thought on the developing pieces of information? we have this new video on screen right now, as they start to inspect the suspect's home and the area around that kerry sanders just telling us that the cordon seems to be broadening as well. what do you think?

>> i think one important clue here is that the individual was supposedly a boxer and the other brother was a wrestler. that my seem just like some sort of athletic pursuit. but that's not irrelevant. having boxed and wrestled myself and having been a federal investigator. these are very closed communities, closed, isolated communities, you have to train with people you trust. i'm sure that the fbi and other law enforcement agencies in region are actively shaking every informant that they can get to get some information. but these tend to be trusted people that you train with. in a sport where potential harm can come to you relatively quickly. that's one important fact. and just a note on the explosives ordinance disposal units. this is unspeakable heroism. i've worked with these gentlemen quite a bit and their motto is find the explosives or function it. and these guys put their lives on the line. i've always appreciated their service. >> don, stand by if you are just joining us this is what we know

at the moment. it is now a standoff, they believe that they have the final suspect holed up, 19-year-old as we, as we look at the information there. in watertown, massachusetts. this 19-year-old, zzhokar sarn ev. that tire town, 32,000 people on lockdown, over a million people being asked to stay indoors in the boston area. >> a train was heading to connecticut. the police symptomed the train and it's headed on to connecticut.

that's what's changed in the last two or three hours. as we look at this, james cavanaugh, they're going door to door in front of this suspect's home. >> you'll see them sweeping the perimeter. making sure there's no bombs or ieds being left or placed under cars. you'll probably see some robot activities if they find a suspicious package. we may not get to see it if we're not close enough. but they'll probably use roekts at the barricaded house if they can get dzhokah to be talking. >> if you're in command of this thing, what clint said, he makes an important point. if dzhokhar is talking with the negotiators and nobody is dying,

everything is good right now. hopefully he's talking and not watching tv. he's just talking to the negotiator, whether it's the massachusetts state police, s.w.a.t. negotiators or atf or fbi. probably a team. >> they're working with him and talking with him and that's good. now the commanders, they've got to have on the tip of their mind, that madrid, spain incident. and they got to remember that that's where the terrorists, when the police came after they did their terrorist bombing campaign, when the police went in, they blew up and committed suicide. so if i was in charge, that case, madrid, would always be on the front of my mind. now, the caveat to that is, is he alone? because if he's alone, it's a barricaded suspect and we need to slow it down and talk and keep madrid on the forefront. if it's somebody in there with him, the whole dynamic changes. but the way we're looking now, this is very positive

development. if he's isolated and he's alone. >> james cavanaugh, as has been said, it is person to person and the linkages between each person as you add, as we add the third person, the question is the third accomplice, what are the connections. roger cressey, we've been watching this new video coming in from cambridge, massachusetts, dogs are there. we were just talking about potential use of robots. we've also seen cycles of activity. kerry sanders, about 30 minutes ago, 40 minutes ago being pushed back successively and now he's saying, it's quieted down a bit. should we expect to see this ebb and flow? >> well, it's always a possibility, richard. i think with the law enforcement officials and the negotiators, if they're involved right now, it's assessing the situation, see what the chances are, if the individual is still alive to get him to surrender. because as james and clint have both said, there is a very real possibility that he will take his own life and attempt to take

the lives of others around. the madrid, the madrid experience is actually an instructive one. and there is always this, this tendency to rush in, and every sense of the word. and if this is a, if this is an individual who has gone through the process of putting together, assembling additional devices, who is planning to do additional attacks, they have to be extremely careful. and we've seen already, he, there is an additional civilian has been murdered. it's highly likely they are going to discover additional devices. so the wait him out component to this, as james and clint have described, is what we might see for the foreseeable future. and you know, we talk about him as, he's a kid. 19 years old, he's a kid. the choices he's going to make right now are going to be influenced by a variety of factors. exhaustion, anger, adrenaline, fear, you can, you can name them all. so this, this could be static

for a very long time. we're just going to have to wait and see. >> roger cressey, stand by, james cavanaugh stand by, one suspect dead, one on the run, dzhokah tsarnaev still at large. i want to thank you for being with us, we'll continue our coverage. right now, alex wagner picks up the coverage. >> i'm alex wagner picking up our coverage of the boston marathon bombing and the manhunt for one of the suspects that has shut down one of america's major cities. a massive manhunt is under way as we said before. for dzhokah tsarnaev, one of the two suspects in the boston marathon bombing, his brother, tamerlan tsarnaev has been killed. dzhokah tsarnaev, who is 19 years old, remains at large. he escaped after the shootout with police, after his brother, tamerlan, apparently wearing an ied strapped to his chest, was killed. people in boston are on
